LAYERED FILM FABRICATION METHOD, LAYERED FILM DEFECT DETECTION METHOD, LAYERED FILM DEFECT DETECTION DEVICE, LAYERED FILM, AND IMAGE DISPLAY DEVICE

摘要

When using a polarizing filter or a check for checking the phase difference filter to carry out the defect inspection of the laminated film with a polarizer is arranged in the member to be disposed in the image-taking optical path in the proper order. A polarizing plate (1) and the optical compensation layer is a failure detection method of the laminated film 11 is laminated, the laminated film 11 and the step of irradiating the light by the light source disposed on a polarizing plate laminated side of the film surface, the film surface of by the image pickup section 12 arranged on the optical compensation layer side, on the basis of the transmitted light image taken by the step of taking a transmitted light image of the laminated film 11, the image pickup section 12, the laminated film (11) in the optical path between has a fault detecting step of performing detection of the defect, the light source 13 and the image pickup section 12 is present in, and check the polarization filter (15) is disposed adjacent to the imaging unit 13, the light source 13 and in the optical path between the imaging unit 12, through the check phase filter (16) disposed between the inspection polarization filter 15 and the laminated film (11) by the image pickup section 12 the imaging is carried out. ; Of the laminated film defect inspection, inspection polarizing filter, a filter for checking the phase difference, a polarizing plate
